Product Description

Product Description

 

A Fourdrinier paper machine generally has seventy or eighty rubber rolls. There are many types of press rolls, which can be divided into  Rubber Press Roll ,Grooved Press Roll , Jumbo Rubber Press Roll, Jumbo Blind Drill Press Roll, Vacuum Suction Press Roll , Press Suction Couch Roll , Suction Pickup roll ,Dryer Felt Roll ,Breast Roll ,Wire Guide Roll, Drive Wire Roll , Suction Touch Roll ,Couch Roll and etc.

dandy roll

Dandy roll is an effective equipment for improve paper uniformity; reduce the difference between the two sides of the paper, enhanced paper physical characteristics. Mainly used in the fourdrinier machine (paper machine speed < 700m/min), with a small investment but be very effective. It is easy for installation and operation. Mostly used in printing and writing paper, special paper, cardboard etc.

Through the technical trial and the actual inspection, the company reserves the right to develop the dandy roll which been successfully used in specialty paper production 650m/min and its effective width also reaches 5660mm. And it's getting on road for the dandy roll design and manufacturing to the higher speed and wider paper machine.

The fourdrinier paper machine assembling the dandy roll has obvious effects on improving the physical properties, surface properties and printability of the paper, especially improving the uniformity of the paper, enhancing the surface fineness, and reducing the beating degree and saving energy consumption. Improve paper yield.

Rubber /Grooved Press Roll

                                                    Rubber /Grooved Press Roll 
                           Max Working Speed : 2000m/min  Maximum Diameter: 1600mm     Maximum Face Length: 14000mm

Rubber Press Roll  is more important to provide good elasticity and ease the pressing effect of the upper press roll on the wet paper and felt, thereby prolonging the service life of the felt and reducing the "compression" of the wet paper.
The elastic encapsulated lower roller can also give the two rollers good contact and uniform dehydration effects, and compensate for the high error of the lower pressure roller.
The rubber hardness of the rubber roller in the production of general paper is usually 70 to 90 Shore hardness. Rubber rollers used for each press in the press section.

Jumbo rubber press roll

Jumbo rubber Press Roll /Blind drill Jumbo Press Roll 

        Max Working Speed : 2200m/min  Maximum Diameter: 1600mm     Maximum Face Length: 120000mm

Jumbo Press roll usually refers to a nip composed of pressing rollers which a diameter of more than 1000mm. It is often used in the production of corrugated paper, cardboard, and other paper or cardboard with large basis weight.
Compared with ordinary presses, it has a wide nip formed by the large-spoke press, the paper sheet can be pressed for a long time in the nip. It can improve the dehydration efficiency, increases the de-watering capacity and paper quantity because of the two-way vertical dehydration design.At the same time, it can also reduce steam consumption in the dryer section and further reduces production costs. The strength and burst resistance of the paper also been improved.
Normally, the paper machine adopts this technology has the feature of high speed, low energy consumption, and good paper quality. Therefore, jumbo pressing technology and equipment have become the first choice in the speed-up and energy-saving of old paper machines and the design of new paper machines.

Vacuum suction press roll

Vacuum Suction Press Roll 

     Max Working Speed : 2000m/min  Maximum Diameter: 1300mm     Maximum Face Length: 10000mm

Vacuum suction press roll is mostly used in medium and high speed paper machines.
The function of the vacuum chamber is only to suck the air in the shell holes. The thicker the roll shell, the more air volume is sucked. Therefore, the use of high-strength metal to make a vacuum suction press roll with a thin roll shell is beneficial to improve the efficiency of press dehydration. The vacuum pressure roller shell is covered with rubber with a thickness of 30-40mm. The advantage of encapsulation is to make the pressure distribution uniform, reduce the abrasion of the felt, and increase the pressure of the press line. Production practice shows that the axial and circumferential center distance of the holes on the vacuum pressure roller is smaller, and the number of holes is larger, which can significantly improve the dehydration effect of the vacuum pressure roller, thereby effectively eliminating the embossing phenomenon and extending the service life of the felt.
